Rwendo urwu rwemakiromita anenge makumi matatu nemakumi mashanu kubva munzvimbo dzawo dzekuzorora kwezhizha rinotora pakati pemwedzi nemwedzi.
Iyo inoita kuti vakadzi vane pamuviri uye vanaamai vane mhuru dzakaberekerwa vatsva vanopedza nguva yakawanda yenguva yavo mumvura inopisa yeHawaii.
Humpback mhuru dzose dziri pamuviri uye dzinoberekwa pedyo neHawaiian Islands. (Nguva yekuzvimirira yevakadzi inenge pakati pemwedzi 10-12.)

Chii chinonzi Humpback Whale?
Iyo humpback whale ndiyo yechishanu yakawanda yenyika huru.
Zita rayo rezvesayenzi, Megaptera novaeangliae, rakapiwa kwairi muna 1781 neGermany anonzi naturalist anonzi Borowski, zvinoreva "Big-Winged New Englander," achitaura nezvehukuru hwemhenga huru yemiswe miviri uye yekuti yakamboonekwa gungwa reNew England.
Ndiro rinowanzozivikanwa zita reChirungu rehumpback rinowonekwa richibva pamhuka yekutenderera yekudzoka shure kwayo pakunyura.
Iyo humpback whale ine grey-yakasviba, bhuruu-yakasviba kune rima rakasvibirira muvara, uye rakasvibirira kumuchena pasi pasi rinogona kuratidza mireza emusiya ayo akasiyana maererano nemumwe munhu whale. Izvo ndezvizvi, uye kunyanya izvo zvakawanikwa mumuswe, kuti munhu mumwe nomumwe nyangadzi anokwanisa kuonekwa uye vanhu uye maitiro akafamba akanyorwa.
Humpback nyangadzo dzinewo mapapiro (kana pectoral fins,) ayo ari kumativi ose emitumbi yavo. Izvo zvinoshandiswa kutendeuka nekufamba. Nyeredzi mhuka dzinopa mhuka, sezvakaita vanhu, uye izvi zvipembenene zviri chaizvo zvakagadziriswa forelimbs, ine pfupa yakafanana neyoruoko rwevanhu neruoko.
Kana akaberekwa, mhuru dzinorema kuenzana kwemaundi 3000 mapaundi uye dzinotangira kubva pamamita gumi nematanhatu pakureba. Dzinokwanisa kukura kusvika pakati pemamita makumi mana nemashanu pakureba, uye vakadzi vacho vari zvishoma kuduku kupfuura varume.
Himbback inokura yakazara inenge imwe tonani pamakumbo, kana inenge 84,000 - 90,000 mapaundi paavhareji. Vatsvakurudzi vanotenda kuti zvipingamupinyi zvinorarama pakati pemakore 40-60.
Chii chinonzi Humpback Whales Kudya?
Humpback nyangadzi dzinowanzofudza mukati memamita 150-160 emvura.
Nzvimbo yeNyakadzi yePacific inoshandisa hove dzepankton kana zviduku zvidzidzo zvakadai se mackerel uye Pacific saury. Nyeredzi dzinosvina zvokudya zvavo kubva pamvura zhinji yakawanda ine hove dzinounzwa mumiromo yavo. Humpback nyangadzi dzakawedzera kukura kwemakumbo emakumbo anowedzera kukwanisa kwemiromo yavo panguva yekudya.
Kana imwe nguva zvokudya zvose zviripo mumuromo, muromo unovharwa uye mvura inomanikidzwa kunze. Munguva iyi, chikafu chinowanikwa mune izvo zvinonzi "baleen plates" uye zvino inowedzwa.
Bareen inokura muhupenyu hwose hwemhawi. Bareen inonziwo whalebone. Bareen inoumbwa nemhando dzakawanda dzezvinhu zvakaoma, zvinoshandiswa zvinoshandiswa zvinosungirirwa kubva kumusha wepamusoro.
Iko mukati mebhanen yakapoteredzwa nemapuranga ane mvere anogadzira plankton, krill nehove duku. Bareen inogadzirwa nekeratin (iyo imwechete zvigunwe zvedu uye vhudzi zvinogadzirwa).
Kunyadziswa kunogona kudya kusvika kune tani yezvokudya mumazuva ezuva. Kazhinji, zvisinei, hazvifudzi panguva yemvura yeHawaii, nzvimbo yavo yechando inobereka.
Unogona Sei Kuona Humpback Whales?
Nzira yakanakisisa yekuona humpback nyangadzi muHawaii ine urongwa hwechikepe hwakarongeka. Nepo kune zvakawanda zvakabayirwa kune imwe neimwe yezvitsuwa zvikuru, zvakanakisisa nechokure ndizvo zvinoshandiswa nePacific Whale Foundation paMaui.
Pacific Whale Foundation isangano risina purogiramu rakagadzirwa muna 1980 kuchengetedza nyangadzi kubva pakuparara.
Nhengo imwe neimwe inofanirwa kutarisa inotarirwa nevanodzidza whale vanozotsanangura zvakadzama maitiro emapuranga uye vanokubatsira kuti uvaone pawindo rako. Pazvikepe zvizhinji iwe uchakwanisawo kunzwa manzwiro chaiwo emhawi mumvura yakapoteredza.
